Every so often, a certain aroma reminds Kentucky State Police Detective Sergeant, William Smith, of his father.
Smith says: "Dad was always chewing gum, and coffee, because there was always coffee cooking."
Smith was only eight years old when his father was killed. His father died in 1973 after he was shot while attempting to arrest a murder suspect.
In honor of his sacrifice, police officers from area agencies are gathering to remember him.
Trooper Todd Holder, with the Kentucky State Police says: "I don't care what color uniform you wear, if it's gray or brown or blue, it doesn't matter, everyone that's fallen in the line of duty is our brother and we look at it that way."
Trooper William Barrett, Detective Darrell Phelps, and Trooper Walter Thurtell were also remembered for their sacrifice.
State police are also honoring fallen officers by lowering flags to half-staff and wearing black bands across their badges.
